Quick Tip

While adding g if the total is 1000 g or more than 1000 g, take 1 to kilogram’s
column as 1 kg = 1000 g. For example, add 1 kg 750 g and 3 kg 300 g.

kg g
Step 1: Add the grams.
1 750
750 + 300 = 1050

+ 3 300 Since 1000 g = 1 kg
1050 Carry over 1 to kg column.

kg g
1 Step 2: Add the kilograms.
1 750
1 + 1 + 3 = 5
+ 3 300 So, 1 kg 750 g + 3 kg 300g = 5 kg 50 g.
